The rehabilitation project will take place adjacent to the Bono Concourse in the Terminal Apron area. Taxiway G is also included in the rehabilitation project. The entire project will occur within the airport property. The projects location is shown on the Vicinity Map in Appendix B This Stormwater Pollution Prevention Plan (SWPPP) is designed to comply with California’s General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities (General Permit) Order No. 2009-0009-DWQ as amended by Order No. 2010-0014-DWQ (NPDES No. CAS000002) issued by the State Water Resources Control Board (State Water Board). This SWPPP was prepared to compliment the Industrial Permit SWPPP (733I001282) currently being implemented that was updated January 31, 2011 and all BMPs described in this SWPPP are in addition to those outlined in the Industrial Permit SWPPP. This SWPPP has been prepared following the SWPPP Template provided on the California Stormwater Quality Association Stormwater Best Management Practice Handbook Portal: Construction (CASQA, 2010). In accordance with the General Permit, Section XIV, this SWPPP is designed to address the following: x Pollutants and their sources, including sources of sediment associated with construction, construction site erosion and other activities associated with construction activity are controlled; x Where not otherwise required to be under a Regional Water Quality Control Board (Regional Water Board) permit, all non-stormwater discharges are identified and either eliminated, controlled, or treated; x Site BMPs are effective and result in the reduction or elimination of pollutants in stormwater discharges and authorized non-stormwater discharges from construction activity to the Best Available Technology/Best Control Technology (BAT/BCT) standard; Calculations and design details as well as BMP controls are complete and correct, and are in Appendix A. This is a Risk Level 1 project and therefore will not require Rain Event Action Plans (REAP’s). 1.2 PERMIT REGISTRATION DOCUMENTS Required Permit Registration Documents (PRDs) shall be submitted to the State Water Board via the Stormwater Multi Application and Report Tracking System (SMARTS) by the Legally Responsible Person (LRP), or authorized personnel (i.e., Approved Signatory) under the direction of the LRP.

CASQA SWPPP Template 9 January 2011 1.7 ANNUAL REPORT The General Permit requires that permittees prepare, certify, and electronically submit an Annual Report no later than September 1st of each year. Reporting requirements are identified in Section XVI of the General Permit. Annual reports will be filed in SMARTS and in accordance with information required by the on-line forms. 1.8 CHANGES TO PERMIT COVERAGE The General Permit allows for the reduction or increase of the total acreage covered under the General Permit when: a portion of the project is complete and/or conditions for termination of coverage have been met; when ownership of a portion of the project is purchased by a different entity; or when new acreage is added to the project. Modified PRDs shall be filed electronically within 30 days of a reduction or increase in total disturbed area if a change in permit covered acreage is to be sought. The SWPPP shall be modified appropriately, shall be logged at the front of the SWPPP and certification of SWPPP amendments are to be kept in Appendix D. Updated PRDs submitted electronically via SMARTS can be found in Appendix E. 1.9 NOTICE OF TERMINATION A Notice of Termination (NOT) must be submitted electronically by the LRP via SMARTS to terminate coverage under the General Permit. The NOT must include a final Site Map and representative photographs of the project site that demonstrate final stabilization has been achieved. The NOT shall be submitted within 90 days of completion of construction. The Regional Water Board will consider a construction site complete when the conditions of the General Permit, Section II.D have been met. CASQA SWPPP Template 10 January 2011 Section 2 Project Information 2.1 PROJECT AND SITE DESCRIPTION 2.1.1 Site Description The Palm Springs International Airport is located south of Interstate 10 in the City of Palm Springs, Riverside County, California. The airport covers 940 acres of land. The terminal apron area is southwest of the runways and surrounds the main terminal and adjoining concrete slab. Taxiway G is located northwest of the main terminal and the air traffic control tower. Palm Springs International Airport is a commercial aviation airport with one existing commercial runway and one existing general aviation runway. The airport lies within the greater Whitewater River Watershed. Runoff from the airport drains to a regional master planned retention basin with 43 acre feet of storage located at the southeastern corner of the airport. A 24 inch storm drain outlet conveys flows from the basin east to the Whitewater River where flows are directed south via stream flow to the Salton Sea. 2.1.2 Existing Conditions As of the initial date of this SWPPP, the project site is comprised of a mixture of impervious surfaces that include concrete and asphalt pavements. The terminal apron area consists of asphalt pavement on aggregate base, while Taxiway G consists of asphalt pavement on alluvial soil. According to Geotracker, there are no historic sources of contamination within the project area. However several historic storage tank facilities along El Cielo Road and North Civic Drive were identified but are not considered a potential source of contamination for construction related activities due to all clean up statuses being complete and all cases closed. 2.1.3 Existing Drainage Onsite surface drainage consists primarily of sheet flow and shallow concentrated flow across the Terminal Apron. Typical drainage patterns are from north to south. Drainage through the terminal apron is conveyed as surface drainage. Existing storm drain inlets located intermittently throughout the area intercept surface runoff and convey flows through a oil/water separator prior to discharging to the Regional Retention Basin. The retention basin is identified in the Palm Springs Master Plan of Drainage and is in place to reduce the amount of flow released from the site. Taxiway G drainage is characterized by sheet flow that drains off the pavement to an adjacent channel that flows east downstream where the flows confluence with the Terminal. As previously mentioned the project discharges to the Whitewater River Wash. The Whitewater River is not identified on the 303 d list as impaired. However the Whitewater River transitions into the Coachella Valley Storm Water Channel that is 303 disted for the following constituents. x DDT x Dieldren x PCBs CASQA SWPPP Template 11 January 2011 x Pathogens x Toxaphene 2.1.4 Geology and Groundwater The site is underlain by artificial fill and alluvium. Locally the soils encountered consisted of poorly graded sands with silt and silty sands with traces of gravel. The artificial fill soils encountered consisted of asphalt and aggregate base. The asphalt ranged from 4 to 12 inches in thickness and the aggregate base ranged from 3 to 8 inches in thickness. In general, the asphalt encountered in the apron area appeared to be fair to poor condition with low to medium severity alligator, block and longitudinal cracking, cracking along utility trenches, rutting, erosions, exposed aggregate and raveling and weathering. The asphalt encountered at Taxiway G was generally in poor condition with moderate to severe alligator and block cracking, rutting and weathering. The alluvial soils encountered during field investigations were relatively course grained and were classified as SM and SP-SM in accordance with the Unified Soils Classification System. These soils are not corrosive to metals, have negligible amounts of sulfates and are non expansive in nature. In general, the upper 3 to 5 feet of the alluvial soils around the terminal apron are dense to very dense. The near surface soils beneath Taxiway G were generally medium dense. According to Websoil Survey soils in the area soils consists of Myoma fine sand. During Geotechnical investigations no springs or areas of natural seepage were found and no groundwater was encountered during subsurface exploration. According to California Department of Water Resources groundwater in the vicinity varies from 170 feet below mean sea level to 195 below mean sea level. 2.1.5 Project Description The rehabilitation and reconstruction project will remove and replace the terminal apron and resurface Taxiway G that will total 34.4 acres. The rehabilitation project is necessary due to the degradation that has occurred to the pavement over the last 30 years. The removal and replacement will consists of several steps. Initially, the existing pavement will be removed, grinded and stockpiled. The substrate below the existing pavement will be tested for bearing capacity and will be removed and recompacted as necessary to meet the required bearing capacity. Depth of excavation is not planned to extend below four feet. There will be no increase to impervious surfaces and the majority of the pavement area will be replaced or resurfaced at existing grade The limits of grading are shown in Appendix B. Preliminary earthwork calculations have demonstrated the project will require net export of soil but exact quantities have yet to be determined. Construction activities will be phased to accommodate airport operations as necessary. 2.1.6 Developed Condition Post construction surface drainage will be managed in the same manner as in the existing condition. Existing hydraulic capacity and grade will maintained in the developed condition. The existing storm drain systems will be utilized in the developed condition. Existing impervious coverage will be maintained in the proposed condition and no new impervious surfaces will be CASQA SWPPP Template 12 January 2011 introduced. Existing drainage infrastructure that includes the inlets, stormdrain, oil water separator and retention basin will be maintained in the developed condition. Post construction drainage boundaries will match existing. Drainage boundaries and conveyance systems are presented in Appendix B. Table 2.1 Construction Site Estimates Construction site area 34.4 acres Percent impervious before construction 100 % Runoff coefficient before construction 0.9 Percent impervious after construction 100 % Runoff coefficient after construction 0.9 2.2 PERMITS AND GOVERNING DOCUMENTS In addition to the General Permit, the following documents have been taken into account while preparing this SWPPP x Regional Water Board requirements x Basin Plan requirements x Contract Documents x Air Quality Regulations and Permits 2.3 STORMWATER RUN-ON FROM OFFSITE AREAS There is no existing offsite run-on to this construction site. 2.4 FINDINGS OF THE CONSTRUCTION SITE SEDIMENT AND RECEIVING WATER RISK DETERMINATION A construction site risk assessment has been performed for the project and the resultant risk level is Risk Level 1. The risk level was determined through the use of the spreadsheet provided by the State Water resources Control Board that accounts for sediment risk and receiving water risk to predict the Risk Level. The sediment risk was determined based on R, K, and LS as defined by the Universal Soil Loss Equation. The R factor was calculated by using Fact Sheet 3.1 provided by the Environmental Protection Agency (EPA). The K factor was determined based on information provided by Websoil Survey. The LS factor was determined based on the average slope through the site (2%) and set to the maximum sheet flow length of 1000 feet. The risk level is based on CASQA SWPPP Template 13 January 2011 project duration, location, proximity to impaired receiving waters and soil conditions. A copy of the Risk Level determination submitted on SMARTS with the PRDs is included in Appendix C. Table 2.2 and Table 2.3 summarize the sediment and receiving water risk factors and document the sources of information used to derive the factors. Table 2.2 Summary of Sediment Risk RUSLE Factor Value Method for establishing value R 12.6 EPA Construction Rainfall Erosivity Waiver K 0.02 Websoil Survey LS 0.69 LS Factors for Construction Sites. Table from Renard et.al., 1997 Total Predicted Sediment Loss (tons/acre) 37.5 Overall Sediment Risk Low Sediment Risk < 15 tons/ acre Medium Sediment Risk >= 15 and < 75 tons/acre High Sediment Risk >= 75 tons/acre Low Medium High Runoff from the project site discharges into natural drainage courses that drain to regional percolation basins. Ultimately the Santa Ana River serves as the receiving body of water. Table 2.3 Summary of Receiving Water Risk Receiving Water Name 303(d) Listed for Sediment Related Pollutant(1) TMDL for Sediment Related Pollutant(1) Beneficial Uses of COLD, SPAWN, and MIGRATORY(1) Whitewater River/Coachella Valley Stormwater Channel Yes No Yes No Yes No Overall Receiving Water Risk Low High (1) If yes is selected for any option the Receiving Water Risk is High Risk Level 1 sites are subject to narrative effluent limitations but are not subject to the numeric effluent standards. The narrative effluent limitations require stormwater discharges associated with construction activity to minimize or prevent pollutants in stormwater and authorized non- stormwater through the use of controls, structures and best management practices. Discharges shall not contain hazardous substances equal to or in excess of reportable quantities established in 40 CFR 117.3 and 302.4. This SWPPP has been prepared to address Risk Level 1 requirements (General Permit Attachment D). 2.5 CONSTRUCTION SCHEDULE The site sediment risk was determined based on construction taking place between June 1, 2013 and September 30, 2014. The construction schedule will be divided into six phases that will CASQA SWPPP Template 14 January 2011 allow for airport operations to continue throughout construction. This schedule will also help to limit the amount of disturbed soil area exposed at any one time. Modification or extension of the schedule (start and end dates) may affect risk determination and permit requirements. The LRP shall contact the QSD if the schedule changes during construction to address potential impact to the SWPPP. The estimated schedule for planned work can be found in Appendix F. 2.6 POTENTIAL CONSTRUCTION ACTIVITY AND POLLUTANT SOURCES Appendix G includes a list of construction activities and associated materials that are anticipated to be used onsite. These activities and associated materials will or could potentially contribute pollutants, other than sediment, to stormwater runoff. The anticipated activities and associated pollutants were used in Section 3 to select the Best Management Practices for the project. Location of anticipated pollutants and associated BMPs are shown in Appendix B. For sampling requirements for non-visible pollutants associated with construction activity please refer to Section 7.7.1. For a full and complete list of onsite pollutants, refer to the Material Safety Data Sheets (MSDS), which should be retained onsite at the construction trailer. 2.7 IDENTIFICATION OF NON-STORMWATER DISCHARGES Non-stormwater discharges consist of discharges which do not originate from precipitation events. The General Permit provides allowances for specified non-stormwater discharges that do not cause erosion or carry other pollutants. Non-stormwater discharges into storm drainage systems or waterways, which are not authorized under the General Permit and listed in the SWPPP, or authorized under a separate NPDES permit, are prohibited. Non-stormwater discharges that are authorized from this project site include the following: x Wind Erosion Control These authorized non-stormwater discharges will be managed with the stormwater and non- stormwater BMPs described in Section 3 of this SWPPP and will be minimized by the QSP. Activities at this site that may result in unauthorized non-stormwater discharges include: x Dewatering x High Pressure Water Blasting It is recommended to allow any standing water after storm events to infiltrate as opposed to pumping the water downstream. In the event that pumping water is necessary the QSP will verify they have the proper permit and will ensure any pumped water is free of sediment. Steps will be taken, including the implementation of appropriate BMPs, to ensure that unauthorized discharges are eliminated, controlled, disposed, or treated on-site. Discharges of construction materials and wastes, such as fuel or paint, resulting from dumping, spills, or direct contact with rainwater or stormwater runoff, are also prohibited.

Applicable BMPs are identified in this section for erosion control, sediment control, tracking control, and wind erosion control. 3.2.1 Erosion Control Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to prevent soil particles from detaching and becoming transported in stormwater runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles. This construction project will implement the following practices to provide effective temporary and final erosion control during construction: 1. The area of soil disturbing operations shall be controlled such that the Contractor is able to implement erosion control BMPs quickly and effectively. 2. Stabilize non-active areas within 14 days of cessation of construction activities or sooner if stipulated by local requirements. 3. Control erosion in concentrated flow paths by applying erosion control blankets, check dams, erosion control seeding or alternate methods. Sufficient erosion control materials shall be maintained onsite to allow implementation in conformance with this SWPPP. The following temporary erosion control BMP selection table indicates the BMPs that shall be implemented to control erosion on the construction site.

Site specific details in the Site Map prevail over standard details included in the Fact Sheets. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets. Scheduling Special consideration will be given to land disturbing activities as to minimize the amount of exposed disturbed soil at any one time. The project will be broken up into six phases in order to minimize the exposed disturbed soil area. Geotextiles and Mats Geotextiles will be anchored with gravel bags over storm drain inlets to reduce the potential for sediment to enter storm drains. Earth Dike and Drainage Swales A concentrated flow path exist down the middle of Taxiway G. The drainage swale will be managed with gravel bags or equivalent as determined by the contractor before likely rain events when in a disturbed state to ensure cutting from erosive flows is minimized and sediment transport downstream is controlled. Velocity Dissipation Devices Velocity dissipation in the form of gravel bags or equivalent should be used within the flow path that runs down the middle of Taxiway G. BMPs should be installed before likely precipitation events to ensure cutting from erosive flows is minimized. Wind Erosion Control Water will be sprayed as necessary from water trucks to control wind erosion. 3.2.2 Sediment Controls Sediment controls are temporary or permanent structural measures that are intended to complement the selected erosion control measures and reduce sediment discharges from active construction areas. Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water. The following sediment control BMP selection table indicates the BMPs that shall be implemented to control sediment on the construction site.

If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard details included in the Site Map. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets. Fiber Rolls Fiber rolls will be placed intermittently throughout the project to intercept runoff, reduce its flow velocity, reduce the runoff as sheetflow and therefore reduce the potential for sheet and rill erosion. Gravel Bag Berm Gravel bags will be used throughout the site to pond sheet flow runoff and allow sediment to settle out. During each phase of construction gravel bags should be placed on the upstream side of the disturbed area boundary to intercept sheet flow and redirect the runoff around the disturbed area. Street Sweeping Street sweeping for the areas around Palm Springs Airport are scheduled for the 1st Friday, 2nd Wednesday, and 3rd Tuesday of every month .Street sweeping will be performed onsite as necessary to remove accumulated sediment and debris. Storm Drain Inlet Protection Inlet protection should be provided around all storm drain inlets. The protection should consists of a fabric that covers the opening that is anchored and secured with gravel bags. Stabilized Construction Entrance and Exit A stabilized construction entrance will be provided for ingress and egress from the site. The ingress/egress will be constructed with rattle plates and large diameter gravel to allow sediment to be dislodged from trucks prior to leaving the site. Any accumulated sediment will be removed immediately. 3.3 NON-STORMWATER CONTROLS AND WASTE AND MATERIALS MANAGEMENT 3.3.1 Non-Stormwater Controls Non-stormwater discharges into storm drainage systems or waterways, which are not authorized under the General Permit, are prohibited. Non-stormwater discharges for which a separate NPDES permit is required by the local Regional Water Board are prohibited unless coverage under the separate NPDES permit has been obtained for the discharge. The selection of non- stormwater BMPs is based on the list of construction activities with a potential for non- stormwater discharges identified in Section 2.7 of this SWPPP. The following non-stormwater control BMP selection table indicates the BMPs that shall be implemented to control sediment on the construction site. Fact Sheets for temporary non- stormwater control BMPs are provided in Appendix H.

If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard details included in the Fact Sheet. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets. Water Conservation Practices All activities that involve the use of water including line flushing and wind erosion control practices should be performed in a manner that avoids causing erosion and the transport of pollutants offsite. The goal of water conservation practices is to reduce or eliminate non- stormwater discharges. Dewatering Operation If accumulated precipitation will cause a significant impact to construction operations there is the potential that dewatering maybe necessary. Any dewatering activities should ensure that water is filtered or otherwise treated for sediment prior to discharge. All effluent is subject to sampling if there is the potential for contaminants to be discharged. Paving and Grinding Operation Paving and grinding activities should entail shoveling or vacuuming saw-cut slurry and removal from site. During AC paving the proper steps should be taken to prevent the discharge of grinding residue, uncompacted or loose AC, tack coats, equipment cleaners, or unrelated paving materials. Illicit Connection- Illegal Discharge Connection Any illicit connections or illegal discharges will be reported to the County Stormwater Hotline at 1-800-506-2555. Vehicle and Equipment Cleaning Cleaning of equipment and vehicles should consider the following: using offsite facilities, washing in designated contained areas only, and eliminating discharges to the storm drain by infiltrating wash water. Vehicle and Equipment Fueling Fueling activities should consider the following: using offsite facilities, fueling in designated areas only, enclosing or covering stored fuel, implementing spill controls, and training employees and subcontractors in proper fueling procedures. Vehicle and Equipment Maintenance Vehicle and equipment maintenance should be performed in designated areas only, while providing cover for materials stored outside, checking for leaks and spills, and containing and cleaning up spills immediately. Concrete Curing Concrete curing should be performed in a manner as to avoid over spraying of curing compounds, minimizing drift by applying close to concrete surface, protecting drain inlets prior to application and using proper storage for compound. CASQA SWPPP Template 24 January 2011 Concrete Finishing Concrete finishing activities should include directing water from blasting away from inlets to collection areas for infiltration or other means of removal, minimizing the drift of dust and blast material by kepping the nozzle close to the surface, disposing of residue as a hazardous waste. High Pressure Water Blasting High pressure water blasting will be performed to remove striping from pavement. A vacuum will follow the high pressure sprayer to remove the spray waste immediately and ensure waste water does not provide a source of non stormwater discharges from the construction site. 3.3.2 Materials Management and Waste Management Materials management control practices consist of implementing procedural and structural BMPs for handling, storing and using construction materials to prevent the release of those materials into stormwater discharges. The amount and type of construction materials to be utilized at the Site will depend upon the type of construction and the length of the construction period. The materials may be used continuously, such as fuel for vehicles and equipment, or the materials may be used for a discrete period, such as soil binders for temporary stabilization. Waste management consist of implementing procedural and structural BMPs for handling, storing and ensuring proper disposal of wastes to prevent the release of those wastes into stormwater discharges. If applicable to the project site, waste management should be conducted in accordance with the Project’s Construction Waste Management Plan. Materials and waste management pollution control BMPs shall be implemented to minimize stormwater contact with construction materials, wastes and service areas; and to prevent materials and wastes from being discharged off-site. The primary mechanisms for stormwater contact that shall be addressed include: x Direct contact with precipitation x Contact with stormwater run-on and runoff x Wind dispersion of loose materials x Direct discharge to the storm drain system through spills or dumping x Extended contact with some materials and wastes, such as asphalt cold mix and treated wood products, which can leach pollutants into stormwater. A list of construction activities is provided in Section 2.6. The following Materials and Waste Management BMP selection table indicates the BMPs that shall be implemented to handle materials and control construction site wastes associated with these construction activities.

If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard details included in the Site Map. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets. Material Delivery and Storage Chemicals should be stored in water tight containers with secondary containment. When hazardous materials are stored on bare soil the area should lined and bermed. Store materials in buildings, vehicles or garages when feasible. Erodible materials should be covered when not in use. Drainage should be directed around all material storage areas. Material Use Material Safety Data Sheets (MSDS) should be supplied for all materials. Training should be provided for all personnel who use hazardous materials. The manufacturers recommendations should be followed for uses, protective equipment, ventilation and mixing of chemicals. Stockpile Management Managing stockpiles is a year around requirement. Stockpiles should be covered if they are not scheduled to be used within 14 days. Drainage should be directed around stockpile areas using sand bags.To properly manage stockpiles Provide description of the site specific implementation or delete if not used Spill Prevention and Control Spills and discharges of spills should be prevented by providing secondary containment, cleaning up spills immediately and properly disposing of spill materials. Solid Waste Management Solid waste should be managed using management procedures and practices designed to prevent or reduce the discharge of pollutants to stormwater from solid or construction waste by providing designated waste collection areas and containers, arranging for regular disposal, and training employees and subcontractors. Hazardous Waste Management Hazardous waste should be managed to prevent or reduce the discharge of pollutants to stormwater from hazardous waste through proper material use, waste disposal, and training of employees, and subcontractors. Contaminated Soil Management Concrete Waste Management Trucks with concrete should be washed out in designated areas only, where washout will not reach stormwater. Washout facilities should be water tight and large enough to contain washout within the designated area. If any discharge from the washout is detected it should be cleaned up immediately. CASQA SWPPP Template 27 January 2011 Sanitary-Septic Waste Management Sanitary and septic waste facilities should be located away from drainage facilities and concentrated flow paths. The facilities should be maintained regularly and fitted with secondary containment trays or equivalent protection. 3.4 POST CONSTRUCTION STORMWATER MANAGEMENT MEASURES Post construction BMPs are permanent measures installed during construction, designed to reduce or eliminate pollutant discharges from the site after construction is completed. This site is located in an area subject to a Phase I or Phase II Municipal Separate Storm Sewer System (MS4) permit approved Stormwater Management Plan. Yes No Post construction runoff reduction requirements have been satisfied through the MS4 program, this project is exempt from provision XIII A of the General Permit. The following source control post construction BMPs to comply with General Permit Section XIII.B and local requirements have been identified for the site: x Pervious Pavement x Bioretention x Infiltration Basins A plan for the post construction funding and maintenance of these BMPs has been developed to address at minimum five years following construction. The post construction BMPs that are described above shall be funded and maintained by East Valley Water District. CASQA SWPPP Template 28 January 2011 Section 4 BMP Inspection, and Maintenance, and Rain Event Action Plans 4.1 BMP INSPECTION AND MAINTENANCE The General Permit requires routine weekly inspections of BMPs, along with inspections before, during, and after qualifying rain events. A BMP inspection checklist must be filled out for inspections and maintained on-site with the SWPPP. The inspection checklist includes the necessary information covered in Section 7.6. A blank inspection checklist can be found in Appendix I. Completed checklists shall be kept in CSMP Attachment 2 “Monitoring Records. BMPs shall be maintained regularly to ensure proper and effective functionality. If necessary, corrective actions shall be implemented within 72 hours of identified deficiencies and associated amendments to the SWPPP shall be prepared by the QSD. Specific details for maintenance, inspection, and repair of Construction Site BMPs can be found in the BMP Factsheets in Appendix H. 4.2 RAIN EVENT ACTION PLANS Rain Event Action Plans (REAPs) are not required for Risk Level 1 projects. CASQA SWPPP Template 29 January 2011 Section 5 Training Appendix L identifies the QSPs for the project. To promote stormwater management awareness specific for this project, periodic training of job-site personnel shall be included as part of routine project meetings (e.g. daily/weekly tailgate safety meetings), or task specific trainings as needed. The QSP shall be responsible for providing this information at the meetings, and subsequently completing the training logs shown in Appendix K, which identifies the site-specific stormwater topics covered as well as the names of site personnel who attended the meeting. Tasks may be delegated to trained employees by the QSP provided adequate supervision and oversight is provided. Training shall correspond to the specific task delegated including: SWPPP implementation; BMP inspection and maintenance; and record keeping. Documentation of training activities (formal and informal) is retained in SWPPP Appendix K.

CASQA SWPPP Template 31 January 2011 6.2 CONTRACTOR LIST Contractor information to be provided once determined Name: Title: Company: Address: Phone Number: CASQA SWPPP Template 32 January 2011 Section 7 Construction Site Monitoring Program 7.1 Purpose This Construction Site Monitoring Program was developed to address the following objectives: 1. To demonstrate that the site is in compliance with the Construction General Permit; 2. To determine whether non-visible pollutants are present at the construction site and are causing or contributing to exceedances of water quality objectives; 3. To determine whether immediate corrective actions, additional Best Management Practices (BMP) implementation, or SWPPP revisions are necessary to reduce pollutants in stormwater discharges and authorized non-stormwater discharges; 4. To determine whether BMPs included in the SWPPP are effective in preventing or reducing pollutants in stormwater discharges and authorized non-stormwater discharges. 7.2 Applicability of Permit Requirements This project has been determined to be a Risk Level 1 project. The General Permit identifies the following types of monitoring as being applicable for Risk Level 1 projects. Risk Level 1 x Visual inspections of Best Management Practices (BMPs); x Visual monitoring of the site related to qualifying storm events; x Visual monitoring of the site for non-stormwater discharges; x Sampling and analysis of construction site runoff for pH and turbidity; x Sampling and analysis of construction site runoff for non-visible pollutants when applicable; and x Sampling and analysis of non-stormwater discharges when applicable. CASQA SWPPP Template 33 January 2011 7.3. Weather and Rain Event Tracking Visual monitoring, inspections, and sampling requirements of the General Permit are triggered by a qualifying rain event. The General Permit defines a qualifying rain event as any event that produces ½ inch of precipitation. A minimum of 48 hours of dry weather will be used to distinguish between separate qualifying storm events. 7.3.1 Weather Tracking The QSP should daily consult the National Oceanographic and Atmospheric Administration (NOAA) for the weather forecasts. These forecasts can be obtained at http://www.srh.noaa.gov/. Weather reports should be printed and maintained with the SWPPP in CSMP Attachment 1 “Weather Reports”. 7.3.2 Rain Gauges The QSP shall install 1 rain gauge on the project site if determined to be necessary by the Regional Board or local agencies. Mount the gauge on a post at a height of 3 to 5 feet with the gauge extending several inches beyond the post. Make sure that the top of the gauge is level. Make sure the post is not in an area where rainwater can indirectly splash from sheds, equipment, trailers, etc. The rain gauge(s) shall be read daily during normal site scheduled hours. The rain gauge should be read at approximately the same time every day and the date and time of each reading recorded. Log rain gauge readings in CSMP Attachment 1 “Weather Records”. Follow the rain gauge instructions to obtain accurate measurements. Once the rain gauge reading has been recorded, accumulated rain shall be emptied and the gauge reset. 7.4 Monitoring Locations Monitoring locations are described in the Sections 7.6 and 7.7. Whenever changes in the construction site might affect the appropriateness of sampling locations, the sampling locations shall be revised accordingly. All such revisions shall be implemented as soon as feasible and the SWPPP amended. Temporary changes that result in a one-time additional sampling location do not require a SWPPP amendment. 7.5 Safety and Monitoring Exemptions To be developed prior to the start of construction. This project is not required to collect to samples or conduct observations under the following conditions: x During dangerous weather conditions x Outside of scheduled business hours CASQA SWPPP Template 34 January 2011 Scheduled site business hours are: Monday - Friday from 7am to 5 pm. If monitoring (visual monitoring or sample collection) of the site is unsafe because of the dangerous conditions noted above then the QSP shall document the conditions for why an exception to performing the monitoring was necessary. The exemption documentation shall be filed in CSMP Attachment 2 “Monitoring Records”. 7.6 Visual Monitoring Visual monitoring includes observations and inspections. Inspections of BMPs are required to identify and record BMPs that need maintenance to operate effectively, that have failed, or that could fail to operate as intended. Visual observations of the site are required to observe storm water drainage areas to identify any spills, leaks, or uncontrolled pollutant sources. Table 7.1 identifies the required frequency of visual observations and inspections. Inspections and observations will be conducted at the locations identified in Section 7.6.3. Table 7.1 Summary of Visual Monitoring and Inspections Type of Inspection Frequency Routine Inspections BMP Inspections Weekly1 BMP Inspections – Tracking Control Daily Erosion and Sediment Control Weekly Non-Stormwater Discharge Observations Quarterly during daylight hours Rain Event Triggered Inspections Site Inspections Prior to a Qualifying Event Within 48 hours of a qualifying event 2 BMP Inspections During an Extended Storm Event Every 24-hour period of a rainevent2 Site Inspections Following a Qualifying Event Within 48 hours of a qualifying event 2 1 Most BMPs must be inspected weekly; those identified below must be inspected more frequently. 2 Inspections are only required during scheduled site operating hours. Note however, these inspections are required daily regardless of the amount of precipitation. 7.6.1 Routine Observations and Inspections Routine site inspections and visual monitoring are necessary to ensure that the project is in compliance with the requirements of the Construction General Permit. 7.6.1.1 Routine BMP Inspections Inspections of BMPs are conducted to identify and record: x BMPs that are properly installed; x BMPs that need maintenance to operate effectively; x BMPs that have failed; or CASQA SWPPP Template 35 January 2011 x BMPs that could fail to operate as intended. 7.6.1.2 Non-Stormwater Discharge Observations Each drainage area will be inspected for the presence of or indications of prior unauthorized and authorized non-stormwater discharges. Inspections will record: x Presence or evidence of any non-stormwater discharge (authorized or unauthorized); x Pollutant characteristics (floating and suspended material, sheen, discoloration, turbidity, odor, etc.); and x Source of discharge. 7.6.2 Rain-Event Triggered Observations and Inspections Visual observations of the site and inspections of BMPs are required prior to a qualifying rain event; following a qualifying rain event, and every 24-hour period during a qualifying rain event. Pre-rain inspections will be conducted after consulting NOAA and determining that a precipitation event with a 50% or greater probability of precipitation has been predicted. 7.6.2.1 Visual Observations Prior to a Forecasted Qualifying Rain Event Within 48-hours prior to a qualifying event a stormwater visual monitoring site inspection will include observations of the following locations: x Stormwater drainage areas to identify any spills, leaks, or uncontrolled pollutant sources; x BMPs to identify if they have been properly implemented; x Any stormwater storage and containment areas to detect leaks and ensure maintenance of adequate freeboard. Consistent with guidance from the State Water Resources Control Board, pre-rain BMP inspections and visual monitoring will be triggered by a NOAA forecast that indicates a probability of precipitation of 50% or more in the project area. 7.6.2.2 BMP Inspections During an Extended Storm Event During an extended rain event BMP inspections will be conducted to identify and record: x BMPs that are properly installed; x BMPs that need maintenance to operate effectively; x BMPs that have failed; or x BMPs that could fail to operate as intended. If the construction site is not accessible during the rain event, the visual inspections shall be performed at all relevant outfalls, discharge points, downstream locations. The inspections should record any projected maintenance activities. 7.6.2.3 Visual Observations Following a Qualifying Rain Event Within 48 hours following a qualifying rain event (0.5 inches of rain) a stormwater visual monitoring site inspection is required to observe: x Stormwater drainage areas to identify any spills, leaks, or uncontrolled pollutant sources; CASQA SWPPP Template 36 January 2011 x BMPs to identify if they have been properly designed, implemented, and effective; x Need for additional BMPs; x Any stormwater storage and containment areas to detect leaks and ensure maintenance of adequate freeboard; and x Discharge of stored or contained rain water. 7.6.3 Visual Monitoring Procedures Visual monitoring shall be conducted by the QSP or staff trained by and under the supervision of the QSP. The name(s) and contact number(s) of the site visual monitoring personnel are listed below and their training qualifications are provided in Appendix K. Assigned inspector: Chris Swonke Contact phone: 909-888-1106 Stormwater observations shall be documented on the Visual Inspection Field Log Sheet (see CSMP Attachment 3 “Example Forms”). BMP inspections shall be documented on the site specific BMP inspection checklist. Any photographs used to document observations will be referenced on stormwater site inspection report and maintained with the Monitoring Records in Attachment 2. The QSP shall submit copies of the completed inspection report to SMARTS directly. The completed reports will be kept in CSMP Attachment 2 “Monitoring Records”. 7.6.4 Visual Monitoring Follow-Up and Reporting Correction of deficiencies identified by the observations or inspections, including required repairs or maintenance of BMPs, shall be initiated and completed as soon as possible. If identified deficiencies require design changes, including additional BMPs, the implementation of changes will be initiated within 72 hours of identification and be completed as soon as possible. When design changes to BMPs are required, the SWPPP shall be amended to reflect the changes.

Sampling for non-visible pollutants will be conducted when (1) a breach, leakage, malfunction, or spill is observed; and (2) the leak or spill has not been cleaned up prior to the rain event; and (3) there is the potential for discharge of non-visible pollutants to surface waters or drainage system. CASQA SWPPP Template 38 January 2011 The following construction materials, wastes, or activities, as identified in the Table below, are potential sources of non-visible pollutants to stormwater discharges from the project. 7.7.1.1 Sampling Schedule Samples for the potential non-visible pollutant(s) and a sufficiently large unaffected background sample shall be collected during the first two hours of discharge from rain events that result in a sufficient discharge for sample collection. Samples shall be collected during the site’s scheduled hours and shall be collected regardless of the time of year and phase of the construction. Collection of discharge samples for non-visible pollutant monitoring will be triggered when any of the following conditions are observed during site inspections conducted prior to or during a rain event. x Materials or wastes containing potential non-visible pollutants are not stored under watertight conditions. Watertight conditions are defined as (1) storage in a watertight container, (2) storage under a watertight roof or within a building, or (3) protected by temporary cover and containment that prevents stormwater contact and runoff from the storage area. CASQA SWPPP Template 39 January 2011 x Materials or wastes containing potential non-visible pollutants are stored under watertight conditions, but (1) a breach, malfunction, leakage, or spill is observed, (2) the leak or spill is not cleaned up prior to the rain event, and (3) there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system. x A construction activity with the potential to contribute non-visible pollutants (1) was occurring during or within 24 hours prior to the rain event, (2) BMPs were observed to be breached, malfunctioning, or improperly implemented, and (3) there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system. x Soil amendments that have the potential to change the chemical properties, engineering properties, or erosion resistance of the soil have been applied, and there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system. x Stormwater runoff from an area contaminated by historical usage of the site has been observed to combine with stormwater runoff from the site, and there is the potential for discharge of non-visible pollutants to surface waters or a storm drain system. 7.7.1.2 Sampling Locations Sampling locations should be based on proximity to planned non-visible pollutant storage, occurrence or use; accessibility for sampling, and personnel safety. If a stormwater visual monitoring site inspection conducted prior to or during a storm event identifies the presence of a material storage, waste storage, or operations area with spills or the potential for the discharge of non-visible pollutants to surface waters or a storm drain system that is at a location not listed above and has not been identified on the Site Maps, sampling locations will be selected by the QSP using the same rationale as that used to identify planned locations. Non-visible pollutant sampling locations shall be identified by the QSP on the pre-rain event inspection form prior to a forecasted qualifying rain event. 7.7.1.3 Monitoring Preparation Non-visible pollutant samples will be collected by: Contractor Yes No Consultant Yes No Laboratory Yes No Samples on the project site will be collected by the following consultant sampling personnel: Name/Telephone Number: / An adequate stock of monitoring supplies and equipment for monitoring non-visible pollutants will be available on the project site prior to a sampling event.

Runoff/downgradient results shall be compared with the associated upgradient/unaffected results and any associated run-on results. Should the runoff/downgradient sample show an increased level of the tested analyte relative to the unaffected background sample, which cannot be explained by run-on results, the BMPs, site conditions, and surrounding influences shall be assessed to determine the probable cause for the increase. As determined by the site and data evaluation, appropriate BMPs shall be repaired or modified to mitigate discharges of non-visible pollutant concentrations. Any revisions to the BMPs shall be recorded as an amendment to the SWPPP. The General Permit prohibits the storm water discharges that contain hazardous substances equal to or in excess of reportable quantities established in 40 C.F.R. §§ 117.3 and 302.4. The results of any non-stormwater discharge results that indicate the presence of a hazardous substance in excess of established reportable quantities shall be immediately reported to the Regional Water Board and other agencies as required by 40 C.F.R. §§ 117.3 and 302.4. Results of non-visible pollutant monitoring shall be reported in the Annual Report. 7.7.2 Sampling and Analysis Plan for pH and Turbidity in Stormwater Runoff Discharges Sampling and analysis of runoff for pH and turbidity is not required for Risk Level 1projects. CASQA SWPPP Template 44 January 2011 7.7.3 Additional Monitoring Following an NEL Exceedance This project is not subject to NELs. 7.7.4 Sampling and Analysis Plan for Non-Stormwater Discharges This Sampling and Analysis Plan for non-stormwater discharges describes the sampling and analysis strategy and schedule for monitoring pollutants in authorized and unauthorized non-stormwater discharges from the project site in accordance with the requirements of the Construction General Permit. Sampling of non-stormwater discharges will be conducted when an authorized or unauthorized non-stormwater discharge is observed discharging from the project site. 7.7.4.1 Sampling Schedule Samples of authorized or unauthorized non-stormwater discharges shall be collected when they are observed. 7.7.4.2 Sampling Locations Samples shall be collected downstream of the area of concern on the construction site. 7.7.4.3 Monitoring Preparation Non-stormwater discharge samples will be collected by: Contractor Yes No Consultant Yes No Laboratory Yes No Samples on the project site will be collected by the following contractor sampling personnel: Name/Telephone Number: An adequate stock of monitoring supplies and equipment for monitoring non-stormwater discharges will be available on the project site.

If the source of an unauthorized non-stormwater discharge is not known, monitoring for pH, turbidity, MBAS, TOC, and residual chlorine or chloramines is recommended to help identify the source of the discharge. Non-stormwater discharge run-on shall be monitored, at minimum, for pH and turbidity. The QSP shall identify additional pollutants to be monitored for each non-stormwater discharge incident based on the source of the non-stormwater discharge. If the source of an unauthorized non-stormwater discharge is not known, monitoring for pH, turbidity, MBAS, TOC, and residual chlorine or chloramines is recommended to help identify the source of the discharge. Table 7.21 lists the specific sources and types of potential non-visible pollutants on the project site and the water quality indicator constituent(s) for that pollutant.

Training records of designated contractor sampling personnel are provided in Appendix K. The stormwater sampler(s) and have received the following stormwater sampling training: Name Training The stormwater sampler(s) and alternates have the following stormwater sampling experience: Name Experience 7.7.7 Sample Collection and Handling 7.7.7.1 Sample Collection Samples shall be collected at the designated sampling locations shown on the Site Maps and listed in the preceding sections. Samples shall be collected, maintained and shipped in accordance with the SWAMP 2008 Quality Assurance Program Plan (QAPrP). Grab samples shall be collected and preserved in accordance with the methods identified in preceding sections. To maintain sample integrity and prevent cross-contamination, sample collection personnel shall follow the protocols below. x Collect samples (for laboratory analysis) only in analytical laboratory-provided sample containers; x Wear clean, powder-free nitrile gloves when collecting samples; x Change gloves whenever something not known to be clean has been touched; x Change gloves between sites; x Decontaminate all equipment (e.g. bucket, tubing) prior to sample collection using a trisodium phosphate water wash, distilled water rinse, and final rinse with distilled water. (Dispose of wash and rinse water appropriately, i.e., do not discharge to storm drain or receiving water). Do not decontaminate laboratory provided sample containers; x Do not smoke during sampling events; CASQA SWPPP Template 49 January 2011 x Never sample near a running vehicle; x Do not park vehicles in the immediate sample collection area (even non-running vehicles); x Do not eat or drink during sample collection; and x Do not breathe, sneeze, or cough in the direction of an open sample container. The most important aspect of grab sampling is to collect a sample that represents the entire runoff stream. Typically, samples are collected by dipping the collection container in the runoff flow paths and streams as noted below. i. For small streams and flow paths, simply dip the bottle facing upstream until full. ii. For larger stream that can be safely accessed, collect a sample in the middle of the flow stream by directly dipping the mouth of the bottle. Once again making sure that the opening of the bottle is facing upstream as to avoid any contamination by the sampler. iii. For larger streams that cannot be safely waded, pole-samplers may be needed to safely access the representative flow. iv. Avoid collecting samples from ponded, sluggish or stagnant water. v. Avoid collecting samples directly downstream from a bridge as the samples can be affected by the bridge structure or runoff from the road surface. Note, that depending upon the specific analytical test, some containers may contain preservatives. These containers should never be dipped into the stream, but filled indirectly from the collection container. 7.7.7.2 Sample Handling Samples for laboratory analysis must be handled as follows. Immediately following sample collection: x Cap sample containers; x Complete sample container labels; x Sealed containers in a re-sealable storage bag; x Place sample containers into an ice-chilled cooler; x Document sample information on the Effluent Sampling Field Log Sheet; and x Complete the CoC. All samples for laboratory analysis must be maintained between 0-6 degrees Celsius during delivery to the laboratory. Samples must be kept on ice, or refrigerated, from sample collection through delivery to the laboratory. Place samples to be shipped inside coolers with ice. Make sure the sample bottles are well packaged to prevent breakage and secure cooler lids with packaging tape. Ship samples that will be laboratory analyzed to the analytical laboratory right away. Hold times are measured from the time the sample is collected to the time the sample is analyzed. The General Permit requires that samples be received by the analytical laboratory within 48 hours of the physical sampling (unless required sooner by the analytical laboratory). Laboratory Name: CASQA SWPPP Template 50 January 2011 Address: City, State Zip: Telephone Number: 7.7.7.3 Sample Documentation Procedures All original data documented on sample bottle identification labels, Effluent Sampling Field Log Sheet, and CoCs shall be recorded using waterproof ink. These shall be considered accountable documents. If an error is made on an accountable document, the individual shall make corrections by lining through the error and entering the correct information. The erroneous information shall not be obliterated. All corrections shall be initialed and dated. Duplicate samples shall be identified consistent with the numbering system for other samples to prevent the laboratory from identifying duplicate samples. Duplicate samples shall be identified in the Effluent Sampling Field Log Sheet. Sample documentation procedures include the following: Sample Bottle Identification Labels: Sampling personnel shall attach an identification label to each sample bottle. Sample identification shall uniquely identify each sample location. Field Log Sheets: Sampling personnel shall complete the Effluent Sampling Field Log Sheet and Receiving Water Sampling Field Log Sheet for each sampling event, as appropriate. Chain of Custody: Sampling personnel shall complete the CoC for each sampling event for which samples are collected for laboratory analysis. The sampler will sign the CoC when the sample(s) is turned over to the testing laboratory or courier. 7.8 Active Treatment System Monitoring An Active Treatment System (ATS) will be deployed on the site? Yes No This project does not require a project specific Sampling and Analysis Plan for an ATS because deployment of an ATS is not planned. The project specific Sampling and Analysis Plan for the ATS is provided in the ATS Monitoring and Sampling Plan (MSRP). 7.9 Bioassessment Monitoring This project is not subject to bioassessment monitoring because it is not a Risk Level 3 project. 7.10 Watershed Monitoring Option This project is not participating in a watershed monitoring option. CASQA SWPPP Template 51 January 2011 7.11 Quality Assurance and Quality Control An effective Quality Assurance and Quality Control (QA/QC) plan shall be implemented as part of the CSMP to ensure that analytical data can be used with confidence. QA/QC procedures to be initiated include the following: x Field logs; x Clean sampling techniques; x CoCs; x QA/QC Samples; and x Data verification. Each of these procedures is discussed in more detail in the following sections. 7.11.1 Field Logs The purpose of field logs is to record sampling information and field observations during monitoring that may explain any uncharacteristic analytical results. Sampling information to be included in the field log include the date and time of water quality sample collection, sampling personnel, sample container identification numbers, and types of samples that were collected. Field observations should be noted in the field log for any abnormalities at the sampling location (color, odor, BMPs, etc.). Field measurements for pH and turbidity should also be recorded in the field log. A Visual Inspection Field Log, an Effluent Sampling Field Log Sheet, and a Receiving Water Sampling Field Log Sheet are included in CSMP Attachment 3 “Example Forms”. 7.11.2 Clean Sampling Techniques Clean sampling techniques involve the use of certified clean containers for sample collection and clean powder-free nitrile gloves during sample collection and handling. Adoption of a clean sampling approach will minimize the chance of field contamination and questionable data results. 7.11.3 Chain of Custody The sample CoC is an important documentation step that tracks samples from collection through analysis to ensure the validity of the sample. Sample CoC procedures include the following: x Proper labeling of samples; x Use of CoC forms for all samples; and x Prompt sample delivery to the analytical laboratory. Analytical laboratories usually provide CoC forms to be filled out for sample containers. An example CoC is included in CSMP Attachment 3 “Example Forms”. 7.11.4 QA/QC Samples QA/QC samples provide an indication of the accuracy and precision of the sample collection; sample handling; field measurements; and analytical laboratory methods. The following types of QA/QC will be conducted for this project: CASQA SWPPP Template 52 January 2011 Field Duplicates at a frequency of 5 percent or 1 duplicate minimum per sampling event (Required for all sampling plans with field measurements or laboratory analysis) Equipment Blanks at a frequency of 1 duplicate minimum per sampling event (Only needed if equipment used to collect samples could add the pollutants to sample) Field Blanks at a frequency of 1 duplicate minimum per sampling event (Only required if sampling method calls for field blanks) Travel Blanks at a frequency of 1 duplicate minimum per sampling event (Required for sampling plans that include VOC laboratory analysis) 7.11.4.1 Field Duplicates Field duplicates provide verification of laboratory or field analysis and sample collection. Duplicate samples shall be collected, handled, and analyzed using the same protocols as primary samples. The sample location where field duplicates are collected shall be randomly selected from the discharge locations. Duplicate samples shall be collected immediately after the primary sample has been collected. Duplicate samples must be collected in the same manner and as close in time as possible to the original sample. Duplicate samples shall not influence any evaluations or conclusion. 7.11.4.2 Equipment Blanks Equipment blanks provide verification that equipment has not introduced a pollutant into the sample. Equipment blanks are typically collected when: x New equipment is used; x Equipment that has been cleaned after use at a contaminated site; x Equipment that is not dedicated for surface water sampling is used; or x Whenever a new lot of filters is used when sampling metals. 7.11.4.3 Field Blanks Field blanks assess potential sample contamination levels that occur during field sampling activities. De-ioninzed water field blanks are taken to the field, transferred to the appropriate container, and treated the same as the corresponding sample type during the course of a sampling event. 7.11.4.4 Travel Blanks Travel blanks assess the potential for cross-contamination of volatile constituents between sample containers during shipment from the field to the laboratory. De-ioninzed water blanks are taken along for the trip and held unopened in the same cooler with the VOC samples. 7.11.5 Data Verification After results are received from the analytical laboratory, the QSP shall verify the data to ensure that it is complete, accurate, and the appropriate QA/QC requirements were met. Data must be verified as soon as the data reports are received. Data verification shall include: CASQA SWPPP Template 53 January 2011 x Check the CoC and laboratory reports. Make sure all requested analyses were performed and all samples are accounted for in the reports. x Check laboratory reports to make sure hold times were met and that the reporting levels meet or are lower than the reporting levels agreed to in the contract. x Check data for outlier values and follow up with the laboratory. Occasionally typographical errors, unit reporting errors, or incomplete results are reported and should be easily detected. These errors need to be identified, clarified, and corrected quickly by the laboratory. The QSP should especially note data that is an order of magnitude or more different than similar locations, or is inconsistent with previous data from the same location. x Check laboratory QA/QC results. EPA establishes QA/QC checks and acceptable criteria for laboratory analyses. These data are typically reported along with the sample results. The QSP shall evaluate the reported QA/QC data to check for contamination (method, field, and equipment blanks), precision (laboratory matrix spike duplicates), and accuracy (matrix spikes and laboratory control samples). When QA/QC checks are outside acceptable ranges, the laboratory must flag the data, and usually provides an explanation of the potential impact to the sample results. x Check the data set for outlier values and, accordingly, confirm results and re-analyze samples where appropriate. Sample re-analysis should only be undertaken when it appears that some part of the QA/QC resulted in a value out of the accepted range. Sample results may not be discounted unless the analytical laboratory identifies the required QA/QC criteria were not met and confirms this in writing. Field data including inspections and observations must be verified as soon as the field logs are received, typically at the end of the sampling event. Field data verification shall include: x Check field logs to make sure all required measurements were completed and appropriately documented; x Check reported values that appear out of the typical range or inconsistent; Follow-up immediately to identify potential reporting or equipment problems, if appropriate, recalibrate equipment after sampling; x Verify equipment calibrations; x Review observations noted on the field logs; and x Review notations of any errors and actions taken to correct the equipment or recording errors. 7.12 Records Retention All records of stormwater monitoring information and copies of reports (including Annual Reports) must be retained for a period of at least three years from date of submittal or longer if required by the Regional Water Board. Results of visual monitoring, field measurements, and laboratory analyses must be kept in the SWPPP along with CoCs, and other documentation related to the monitoring. Records are to be kept onsite while construction is ongoing. Records to be retained include: CASQA SWPPP Template 54 January 2011 x The date, place, and time of inspections, sampling, visual observations, and/or measurements, including precipitation; x The individual(s) who performed the inspections, sampling, visual observation, and/or field measurements;

Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments.

75 tons/acre Sediment Risk Factor Worksheet A) R Factor R Factor Value B) K Factor (weighted average, by area, for all site soils) Analyses of data indicated that when factors other than rainfall are held constant, soil loss is directly proportional to a rainfall factor composed of total storm kinetic energy (E) times the maximum 30-min intensity (I30) (Wischmeier and Smith, 1958). The numerical value of R is the average annual sum of EI30 for storm events during a rainfall record of at least 22 years. "Isoerodent" maps were developed based on R values calculated for more than 1000 locations in the Western U.S. Refer to the link below to determine the R factor for the project site. http://cfpub.epa.gov/npdes/stormwater/LEW/lewCalculator.cfm K Factor Value LS Factor Value Low C) LS Factor (weighted average, by area, for all slopes) The soil-erodibility factor K represents: (1) susceptibility of soil or surface material to erosion, (2) transportability of the sediment, and (3) the amount and rate of runoff given a particular rainfall input, as measured under a standard condition. Fine-textured soils that are high in clay have low K values (about 0.05 to 0.15) because the particles are resistant to detachment. Coarse-textured soils, such as sandy soils, also have low K values (about 0.05 to 0.2) because of high infiltration resulting in low runoff even though these particles are easily detached. Medium-textured soils, such as a silt loam, have moderate K values (about 0.25 to 0.45) because they are moderately susceptible to particle detachment and they produce runoff at moderate rates. Soils having a high silt content are especially susceptible to erosion and have high K values, which can exceed 0.45 and can be as large as 0.65. Silt-size particles are easily detached and tend to crust, producing high rates and large volumes of runoff. Use Site-specific data must be submitted. The effect of topography on erosion is accounted for by the LS factor, which combines the effects of a hillslope-length factor, L, and a hillslope-gradient factor, S. Generally speaking, as hillslope length and/or hillslope gradient increase, soil loss increases. As hillslope length increases, total soil loss and soil loss per unit area increase due to the progressive accumulation of runoff in the downslope direction. As the hillslope gradient increases, the velocity and erosivity of runoff increases. Use the LS table located in separate tab of this spreadsheet to determine LS factors. Estimate the weighted LS for the site prior to construction. 0.17388 Site-specific K factor guidance LS Table Receiving Water (RW) Risk Factor Worksheet Entry Score A.
